80-Year-Old Rupert Murdoch Joins the Twittersphere - Backs Santorum?

LONDON (The Blaze/AP) — Yes, it really is Rupert Murdoch — and not an impostor — on Twitter.

A man using the media mogul's name started tweeting over the New Year's holiday, and a spokeswoman at his News International company confirmed Monday the account -- @rupertmurdoch -- is genuine.

The embattled chief of the sprawling News Corp. media conglomerate says on Twitter that his resolutions for 2012 are to "try to maintain humility" and to diet.

The 80-year-old added that he wants to stay curious. He also sounds bored with his holiday: "Back to work tomorrow," he says. "Enough idling!"

The Sydney Morning Herald (via Business Insider) reports that Murdock recently used the microblogging site to criticize the British for perhaps having too many holidays:

''Maybe Brits have too many holidays for broke country!'

This tweet was deleted shortly after. Here are a few of Murdoch's other recent tweets:

In just three days, Murdoch already has more than 64,000 followers.

Murdoch may face questioning later this year from the Leveson Inquiry, which is investigating criminal wrongdoing at Murdoch's British newspapers, including the now-closed News of the World tabloid.

NY Times:

The media mogul Rupert Murdoch signaled his support for Rick Santorum on Monday evening, calling him the “only candidate with genuine big vision” for the United States.

His comments were significant not only because Mr. Murdoch controls Fox News Channel and The Wall Street Journal, but also because they were made on Twitter, a Web site that allowed for his support to be forwarded far and wide on the eve of the Iowa caucuses. Mr. Santorum was a paid analyst for Fox News before he announced his bid for the presidency last year.

Mr. Murdoch seemed to stop short of an outright endorsement. “Can’t resist this tweet,” he wrote, “but all Iowans think about Rick Santorum.” It was unclear if he was saying that all Iowa voters are thinking about Mr. Santorum, or should be thinking about him.
